Ununseptium is the systematic element name for the chemical element with the atomic number 117, Chemical symbol Uus.
Ununseptium is an artificial chemical element, radioactive, unstable, atomic number 117, having two isotopes; it is supposed that Uus is a halogen but with only six atoms obtained is difficult to be sure now.
Chemical Properties If it reacts (reactivity) If it corrodes (corrosion) Physical Properties malleable ductile conductivity magnetic
Flourine belongs to a class of elements called Halogens, which are similar in their chemical and physical properties. The other elements of this group are Chlorine, Bromine, Iodine, Astatine and Ununseptium. Astatine, however, is not considered to be a true halogen since it is radioactive in nature and Ununseptium is a synthetic element.
No. Chemical and physical properties are different.
Ununseptium is an artificial chemical element.
Physical and chemical properties change as the result of a chemical change, which produces new products with different physical and chemical properties than the reactants.
Some predicted properties of ununseptium:- melting point: 300-500 0C- boiling point: 55 0C- density: 7,2 g/cm3- empirical atomic radius; 138 PM- first ionization energy: 742,9 kJ/mol- solid- atomic number: 117- radioactive- unstableThe chemistry of Uus is not known.

A chemical change is when the chemical properties of a substance changes and a physical change is when the chemical properties stay the same but the physical properties (shape, temperature etc...)
Batteries store energy in chemical form and convert it to electrical energy. They have physical properties such as size, weight, and shape, as well as chemical properties including the types of materials used in the electrodes and electrolyte. Key characteristics include voltage, capacity, energy density, discharge rate, and cycle life.
